Combining for best efficiency you could potentially produce enough energy for both your home and have excess that could be sold back to the utility companies. But don't go overboard and have such a large setup thinking you can make a fortune selling energy back. In most cases the amount that you get paid per kilowatt is low to the point that it is not worth it to attempt to make money from. It is best to just have enough produced to power your home and keep your batteries topped off.
So let's recap. To totally run your home on solar, your set up cost would be a little over $50,000. To install wind power, which would cut your cost of electricity down 50%-90%, would cost $20,000.
Wind cost of install on average $20,000 to provide 75% of your energy.
Solar Energy Estimates $40,000 dollars to fully power your entire house with a little to spare. Now divide by 2 because you will only need half of that.
TOTAL COST= $40,000
Total Cost/Approx incentives reduction
$40,000/50%*= $20,000 To fully power your entire house with green electricity.
With an average electric bill of around $125.00 per month you would recoup your investment in around 160 months or around 14 years (this is also not counting any excess electricity you produce and sell back to the utility company). Also keep in mind you're doing this to be more environmentally friendly and aid our environment which is a big plus by itself.
*Please note these are only estimates and are subject to vary from state to state and year to year. The estimated reduction in cost with all incentives included is an approximate a 50% reduction.
